IMPROVEMENT IN BRUSHES.

Specification forming part of Letters Patent No. 222,166, dated December2, 1879; application filed September 16, 1879.

To all whom it may concern:

Beit known that we, GEORGE WADSWORTH, of Boston, in the county ofSuffolk and State of Massachusetts, and JOSEPH B. SMITH, of New York, inthe county and State of New York, have invented a new and usefulImprovement in Brushes, of which the following is a specification.

Our invention relates to an improvement in the class of bristle-brushessuch as are used for painting, whitewashing, &c.; and it consists in theconstruction and arrangement of parts as hereinafter described, wherebythe bristles are firmly secured to the stock or head, and a superiorbrush produced economically.

- It consists in providing the stock with a dovetailed core, along whichthe butts of the bristles are-laid and secured by wooden strips oneachside held under a metal ferrule .securely fastened to the core outsideof the bristles.

In the accompanying drawings, Figure 1 is a sectional side elevation ofmy improvement in brushes, and Fig. 2 is a vertical cross-section ofFig. 1 on linear .00.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A is the fiat stock of the brush providedwith a handle, B, and having on its bottom edge a dovetailed projection,O, forming the core. Above the shoulders to a grooves 12 are made in thesides of the stock.

D is the ferrule made in two parts, which hence may be easily andquickly attached or detached. This facility of attachment anddetachment, coupled with the facts that the core 0 does not require tobe perforated nor the bristles to be secured thus by means of nailsorcord, greatly economizes the labor of constructing the brush ascompared with others of its class. I

Lips d are formed on the lower edges of the plates D, which, togetherwith the angular lateral projection of the core 0, hold the strips E inplace.

The upper edges of the sides of the ferrule are turned over inwardly atright angles, forming flanges e c, which are adapted to be fitted intothe grooves 11 b. A head or rib, f, is struck outwardly in the sides ofthe ferrule to give stiffness to the sides.

The manner of operating our invention is as follows: The butts of thebristles E are laid along the sides of the dovetailed projection O andaronndzthe ends t-hereof,'with their extreme ends abutted against theshoulders a, as shown in the drawings. \Vhen they have been laid intothe proper thickness the ferrule is put in place with the wooden stripsagainst the bristles, and the lips d compressing the bristles againstthe broad edges of the dovetail, and the flanges c e in the grooves b,and when the two parts of the ferrule have been pressed up against thebristles with sufficient force, the ends are joined together and nailedto the core, as before described.

By the construction and arrangement of parts above described, we producecheaply a brush whose bristles are held very securely by the coaction ofthe angles of the core 0, the elastic metallic plates D and elasticwooden strips E;

We do .not claim, broadly, the use of elastic 1netallic plates for thispurpose, and we are aware a brush has been provided with a core havinginclined sides, but, not with the acute angle of ours. I I

Having thus described our invention, W

claim as new and desire to secure by Letters Iatent In a brush, thecombination, with the wooden core G, having an acute angle at its loweredge, oi the elastic metallic side plates, D D, constituting theferrule, and the wooden strips E E, which are placed between said platesand core, as shown and described, for the purposespecilied.
